Air Filter, Separator, Oil Separator, Water Drainer AF804 FILTRATION DEGREE - 5 MICRONS, OR 0.005mm. This filtration degree is EIGHT TIMES more precise than the simplest models with 40-micron filters - ensuring the capture of most contaminant particles. This filter is used to dry air. It is an essential element of every pneumatic system. By using this filter, you prevent, among other things, rusting of tools, streaks during painting with spray guns, damage to hoses, etc. The filter does not require additional mounting; it is held on the nipple or coupling that will be attached to the compressor. Draining the water is accomplished by pulling the valve located at the bottom of the filter. It also separates oil and other contaminants. It is equipped with a metal tank cover.
